FAQs: Overview of Encoder
What does 1920*1080P@30HZ mean?
If it shows 1920*1080P@30HZ on GUI, probably it's failed to detect the HDMI signal. Take the following steps if there is a failure to detect an HDMI signal. Ensuring that the HDMI cable is properly connected and meets the necessary requirements, as well as checking and adjusting the output resolution of the HDMI signal, can often resolve detection issues.
If the HDMI detection issue persists despite checking the cable and resolution, it could be related to the Extended Display Identification Data (EDID). The EDID is information provided by a display to the source device, and issues with EDID communication can result in detection failures. In such cases, troubleshooting the EDID communication and potentially getting the log when you're trying to connect this HDMI may be helpful for us to help you resolve the detection problem.

What could be the reason for the failure to detect an HDMI signal from a Rapberry PI?
If you're encountering issues with detecting an HDMI signal from a Raspberry Pi, it's advisable to consider adjusting the audio input from HDMI to Line-in. The reason for this recommendation lies in the dynamic nature of audio on Raspberry Pi devices. When the audio fluctuates, if the encoder continually uses HDMI input for audio, it will repeatedly attempt to detect the HDMI signal whenever changes occur. By switching to Line-in for the audio input, this perpetual detection process is avoided, offering a more stable signal. This approach differs from connecting the Raspberry Pi to a TV, where audio and video are simply displayed. For the encoder, both the video and audio need to be encoded together with the HDMI signal, and this adjustment is crucial for optimal performance.
Why does my encoder fail to detect the HDMI signal from my computer with an output resolution of 1366x768?
If the HDMI output resolution of the computer is set to 1366x768, the encoder typically cannot detect this video resolution. This limitation arises because the encoder's main chip processes video resolutions based on specific mathematical calculations, and 1366 divided by 4 is not an integer. As a result, the encoder is unable to handle this resolution, making it incompatible with the current hardware and firmware design.
To resolve this issue, it is recommended to adjust the HDMI output resolution to a standard format supported by the encoder, such as 1280x720 (720p) or 1920x1080 (1080p). These resolutions are widely supported and ensure that the video signal can be properly detected and encoded without issues.
This incompatibility highlights the importance of selecting resolutions that align with the encoder's technical specifications to achieve seamless video processing and transmission.
Why is the default HDMI output resolution set to 1920x1080P@60Hz on my 4K encoder?
If the default HDMI output resolution is 4K (3840x2160), there might be issues displaying it correctly on most monitors. This is because the default display resolution for most monitors is 1920x1080. Monitors that do not support resolutions higher than 1080p may not be able to show content properly, potentially causing distortion or loss of clarity.
However, if you wish to display 4K (3840x2160) content, you can adjust the output resolution by navigating to System Settings and selecting Video Output Format. This change allows the encoder to output 4K resolution, ensuring that the video displays correctly on monitors that support higher resolutions. It's important to make sure that your monitor can handle 4K resolution to view the content without any issues.
Why is my encoder unable to detect the HDMI signal from my PC when using a DisplayPort (DP) to HDMI converter?
Typically, HDMI encoders do not provide power output to external devices, such as a DisplayPort to HDMI converter. As a result, the encoder may fail to detect the video signal if the converter is not powered externally. To resolve this issue, you should ensure that the DisplayPort to HDMI converter you're using has its own external power source. Without external power, the converter might not function properly, and the encoder will not be able to detect the video signal.
NOTE: It's same for VGA to HDMI converter too. The issue of HDMI encoders not detecting video signals also applies to VGA to HDMI converters, as they typically don't provide power to the video converter. Using a VGA to HDMI converter with external power would resolve this issue.
Why doesn’t my HDMI encoder automatically play after switching sources with an HDMI switcher like Kramer?
When using an HDMI switcher like the Kramer HDMI switcher, it is generally recommended to reboot the HDMI encoder after switching to a new video source. This is because the HDMI chip in the encoder needs to perform further detection to properly recognize and process the newly selected input signal. Rebooting ensures a fresh initialization and stable operation, preventing potential issues with signal detection or streaming. This step is especially helpful when dealing with switchers that handle multiple sources or rapid source changes.
